.... it's one long weekend.
Good Friday (which is a national holiday. Indians give themselves holidays for everyone's festivals ... :))
Holi (big Hindu spring festival, involving young folks going around dumping color on each other. Tons of fun. And, in traditional circles, one of the few times the sexes can mix.) which is really celebrated over two days, the second day (Dhuleti) being the fun stuff.
Eid-e-Milad (or Milad an-Nabi), the birthday of the Prophet
Nowrouz, the Parsi (Zoroastrian) New Year.
All this weekend.
[In addition, the Jewish people celebrate Purim this weekend. Not too many Jews left in India though ...]
